Vigorous and rapid air exchanges might not always be a good thing when it comes to levels of coronavirus particles in a multiroom building, according to a new modeling study. Particle levels can spike in downstream rooms shortly after rapid ventilation.

Researchers at the Institute for Bioengineering of Catalonia (IBEC) led by Samuel Sanchez achieve a breakthrough in the field of biological robots by developing new biobots based on muscle cells that can swim at unprecedented velocities. These biobots also react to electrical stimuli and exert surprising forces thanks to their self-training with a 3D printed smart skeleton, opening the door to a new generation of stronger and faster biological robots based on muscle cells.

Nagoya University researchers and colleagues have uncovered a molecular pathway that enhances chemotherapy resistance in some pancreatic cancer patients. Targeting an RNA to interrupt its activity could improve patient response to therapy and increase their overall survival.

A new paper is the first to study the effects of advanced shoe technology on the performance of elite long-distance runners. Researchers found that the new footwear, featuring lightweight foam and a rigid plate in the midsole, significantly reduced race times for both men and women. Female runners benefited most, shaving about 2 minutes and 10 seconds off marathon times, which represents a 1.7 percent boost in performance.

Kobe University Hospital's Dr. NISHIMORI Makoto and Project Assistant Professor KIUCHI Kunihiko et al. have developed an AI that uses multiple kinds of test data to predict the location of accessory pathways, which cause the heart to beat irregularly. The researchers were able to improve diagnosis accuracy by having the AI learn from two completely different types of test results- electrocardiography (ECG) data and X-ray images. It is hoped that this methodology can be applied to other disorders.

Survey of 3,536 healthcare workers suggests 67 percent are suffering burnout, but people who receive frequent COVID-19 tests are less likely to be burned out.

Time seems to pass more slowly in the UK COVID-19 lockdown - especially for people who are depressed, shielding or dissatisfied with social interactions.

Substantial proportions of pregnant and postpartum women scored high for symptoms of anxiety, depression, loneliness and post-traumatic stress in relation to COVID-19 in a survey carried out in May and June 2020, according to a new study published this week in the open-access journal PLOS ONE by Karestan Koenen and Archana Basu of Harvard T.H. Chan School of Public Health, US, and colleagues.

High-temperature superconductors are famous for conducting electricity with no loss, but no one knows how they do it. Now SLAC scientists have observed the signature of an exotic state of matter called "pair density waves" in a cuprate superconductor and confirmed that it intertwines with another exotic state -- a step toward understanding how these materials work.

Guilt and social pressure lead people to underreport COVID-19 protocol violations, according to study of experimental data across 12 countries.

Nodal lines are degeneracies formed by crossing bands in three-dimensional momentum space. These degenerate lines can further form into nodal chain and nodal link. The authors proposed and demonstrated a novel type of stable in-plane nodal chain specific to photonics. They also developed nodal link in momentum space which exhibits non-Abelian characteristics on a C2T - invariant plane. The admissible transitions of the nodal link structure are determined by generalized quaternion charges.

An increasing number of young women are at increased risk of having children born with impaired neurological conditions, due to poor iodine intake.

A mitochondrial peptide called MOCCI has a surprising sidekick, and they work together to regulate inflammation and immunity, Singapore researchers reveal.

Invasive Group B Streptococcus (GBS) disease, notably meningitis, during the first days and months of a baby's life can have persistent effects for children and hence their families, according to new research. Published in the Lancet Child & Adolescent Health, the study is the first evidence of long-term effects including after GBS sepsis (infection in the bloodstream).

A new study has found up to half of all children with language difficulties and mental and physical health problems have been exposed to intimate partner violence, prompting calls for health and social care services to provide more effective identification and early intervention.

The antibody drug conjugate sacituzumab govitecan performed significantly better than single-agent chemotherapy in a phase 3 clinical trial. Researchers aim to combine antibody drug conjugates with other agents and move them to first-line or even earlier therapies--to not just treat but also help prevent metastatic triple-negative breast cancer.

New legislation would increase oversight of laboratory-developed tests. Until now, the potential impact on health care costs of this legislation was unknown. The economic effects will depend on how the law is interpreted, a new study shows.

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory and the University of Illinois Urbana-Champaign have developed a new mathematical model for predicting how epidemics such as COVID-19 spread. This model not only accounts for individuals' varying biological susceptibility to infection but also their levels of social activity, which naturally change over time.

Skoltech scientists in collaboration with researchers from the University of Arizona and the Los Alamos National Laboratory have developed an approach that allows power grids to return to stability fast after demand response perturbation.

Cisgender sexual minority men and transgender women are aware of pre-exposure prophylaxis (PrEP), a daily pill for HIV-negative people to prevent HIV infection, but few are currently taking it, according to researchers at Rutgers.The study, published in the journal AIDS and Behavior, surveyed 202 young sexual minority men and transgender women - two high-priority populations for HIV prevention - to better understand why some were more likely than others to be taking PrEP.
